前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件是GB/T6974《起重机术语》的第3部分。GB/T6974已经发布了以下部分：

——第1部分：通用术语；

——第2部分：流动式起重机；

——第3部分：塔式起重机；

——第4部分：臂架起重机；

——第5部分：桥式和门式起重机；

——第6部分：铁路起重机；

——第7部分：浮式起重机。

本文件代替GB/T6974.3—2008《起重机术语第3部分：塔式起重机》，与GB/T6974.3—

2008相比，除结构调整和编辑性改动外，主要技术变化如下：

a）更改了范围（见第1章，2008年版的第1章）；

b）增加了术语“组装式塔式起重机”“自行架设式塔式起重机”和“流动式自行架设的塔式起重

机”及其定义（见3.1.1、3.1.2和3.1.3）；

c）更改了不同类型的塔式起重机的示例图（见第5章，2008年版的第4章）。

本文件等同采用ISO4306⁃3：2016《起重机术语第3部分：塔式起重机》。

本文件增加了“规范性引用文件”一章。

引言

术语的标准化是标准化活动的基础。GB/T6974《起重机术语》作为起重机专业领域的术语标

准，在提升起重机标准化水平，保证术语的一致性和逻辑的完整性，提升概念体系间以及不同语种术语

间的协调性，促进技术交流和商贸合作等方面发挥着重要作用。GB/T6974拟由9个部分构成。

——第1部分：通用术语。目的在于规范适用于起重机行业领域的通用术语和定义。

——第2部分：流动式起重机。目的在于规范流动式起重机相关的术语和定义。

——第3部分：塔式起重机。目的在于规范塔式起重机相关的术语和定义。

——第4部分：臂架起重机。目的在于规范臂架起重机相关的术语和定义。

——第5部分：桥式和门式起重机。目的在于规范桥式和门式起重机相关的术语和定义。

——第6部分：铁路起重机。目的在于规范铁路起重机相关的术语和定义。

——第7部分：浮式起重机。目的在于规范浮式起重机相关的术语和定义。

——第8部分：缆索起重机。目的在于规范缆索起重机相关的术语和定义。

——第9部分：电气。目的在于规范起重机电气相关的术语和定义。
